Description
Technical field
The utility model relates to a kind of capstan winch, relates in particular to a kind of engaging and disengaging gear of capstan winch.
Background technology
Capstan winch is the self-protection and the draw gear of vehicle, ship, can in harsies environment such as snowfield, marsh, desert, seabeach, muddy hill path, save oneself and sue and labour, and be the indispensable safety devices of outdoor exercises.Capstan winch can be at level or acclive ground drawbar load, also vertical hook load.Capstan winch relies on being connected of load and is fixed on the rope on the elevator axle, is generally steel rope or nylon rope.During work, power is delivered to the elevator axle through speed reduction gearing and draws object, and in order to increase moment of torsion, speed generally is reduced to below the 5m/min.In order to increase work efficiency, generally all be provided with engaging and disengaging gear, the elevator axle is separated with transmission device, the ability independent rotation, thus rope can freely pull out.
The engaging and disengaging gear kind is a lot, need select by machine construction.In the capstan winch industry, the satellite gear transmission is because its reduction ratio is big, advantage such as volume is little, bearing capacity is big and use more.Planetary wheeling assembly comprises center gear, satellite gear, pinion carrier, internally toothed annulus etc.Through separating the pinion carrier or the center gear of transmission shaft and planetary wheeling assembly, fixing internally toothed annulus is freely turned round, can reach the purpose that transmission device separates with the elevator axle.
Summary of the invention
The technical matters that the utility model will solve provides a kind of engaging and disengaging gear of capstan winch, and it can make the elevator axle separate with the satellite gear transmission device of capstan winch.
The engaging and disengaging gear of the capstan winch of the utility model comprises:
One casing, its internal fixation is provided with an inner gear, and this inner gear is provided with knock hole;
One satellite gear assembly, it is located in the casing;
One internally toothed annulus, it is sheathed on the periphery of this planetary wheeling assembly, and the side of this internally toothed annulus is provided with breach;
One step cutting pattern shape is pulled pin, and it is located in this knock hole, stage clip of end cover that its external diameter is little, and the end that external diameter is big is against on the side of internally toothed annulus;
One drag-line, it links to each other with pulling pin.
Said planetary wheeling assembly comprises one-level planetary wheeling assembly, secondary planet wheel assembly and the third-level planetary wheel assembly that links to each other successively; This one-level planetary wheeling assembly and secondary planet wheel assembly are located in the said inner gear, and said internally toothed annulus is sheathed on the periphery of this third-level planetary wheel assembly.
Said breach is a plurality of, and it is symmetrically distributed in the side of this internally toothed annulus.
The engaging and disengaging gear of the capstan winch of the utility model; When not having M/C elevator axle; The major part of pulling pin possibly be against the outside or the indentation, there of internally toothed annulus, and when dynamic drive third-level planetary wheel assembly rotated, internally toothed annulus can both stop operating; Power can be delivered to sprocket shaft, and then is delivered to the elevator axle; When needs M/C elevator axle, the pulling drag-line will be pulled pin and in internally toothed annulus, pulled out, and pull pin and the outside of internally toothed annulus keeps released state, and internally toothed annulus is free to rotate, and this moment, sprocket shaft was free to rotate, and then the elevator axle is also free to rotate.The engaging and disengaging gear of the capstan winch of the utility model has kept internally toothed annulus intensity because the side of internally toothed annulus is provided with plural breach, reduces mechanical breakdown, realizes the remote handing of clutch function.

Fig. 2 is the exploded view of engaging and disengaging gear of the capstan winch of the utility model;
Fig. 3 is the section-drawing of engaging and disengaging gear of the capstan winch of the utility model.
The specific embodiment
Combine accompanying drawing and embodiment that the utility model is done further explain at present.
Referring to Fig. 1, Fig. 2 and Fig. 3, the engaging and disengaging gear of the capstan winch of the utility model comprises a casing 10, and its internal fixation is provided with an inner gear 20; Be provided with one-level planetary wheeling assembly 21 and secondary planet wheel assembly 22 in the inner gear 20; Third-level planetary wheel assembly 30 is connected with secondary planet wheel assembly 22; At a peripheral sheathed internally toothed annulus 40 of the satellite gear of third-level planetary wheel assembly 30, the side of this internally toothed annulus 40 is symmetrical set plural breach 41, and inner gear 20 is provided with a knock hole 201; Be provided with a step cutting pattern shape in this knock hole 201 and pull pin 211; Stage clip 210 of the little end of its external diameter cover, the end that external diameter is big is against on the breach 41 of internally toothed annulus 40, and a drag-line 60 211 links to each other with pulling pin.
The elevator axle links to each other with sprocket shaft 70, and sprocket shaft 70 links to each other with third-level planetary wheel assembly 30.
The operation of engaging and disengaging gear is following: when not having M/C elevator axle, 211 major parts of pulling pin possibly be against the outside or breach 41 places of internally toothed annulus 40.When dynamic drive third-level planetary wheel assembly 30 rotates, 211 be stuck in breach 41 places if pull pin, internally toothed annulus is motionless, and kinetic force is transferred to sprocket shaft 70, and then is delivered to the elevator axle; 211 are against internally toothed annulus 40 outsides if pull pin, and satellite gear drives the internally toothed annulus rotation, behind the rotation certain position; Pull pin and 211 fallen in internally toothed annulus 40 breach 41 by stage clip 210 power; Internally toothed annulus is stopped operating, and power also can be delivered to sprocket shaft 70, and then is delivered to the elevator axle.
When needs M/C elevator axle, pulling drag-line 60 will be pulled pin and 211 in internally toothed annulus 40, pulled out, and pull pin and 211 keep released state with the outside of internally toothed annulus 40.Internally toothed annulus 40 is free to rotate, and this moment, sprocket shaft 70 was free to rotate, and then the elevator axle is also free to rotate.
The engaging and disengaging gear of the capstan winch of the utility model improves internally toothed annulus 40 intensity because the side of internally toothed annulus 40 is provided with plural breach 41, reduces mechanical breakdown, realizes the remote handing of clutch function.
The above only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Though the utility model discloses as above with preferred embodiment; Yet be not in order to limiting the utility model, anyly be familiar with the professional and technical personnel, in the scope that does not break away from the utility model technical scheme; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be the content that does not break away from the utility model technical scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technical scheme according to the technical spirit of the utility model.
